Concrete underground storage container crack and overrun prevention? I am building my own underground storage tank (UST) out of concrete...
I am building my own underground storage tank (UST) out of concrete and have hear that the tank can crack, creating leaks and loosing hose. I would like to know if there is a style to prevent this from happening...? thanks!
the concrete should only be a containment (secondary) tank.
your primary reservoir should be fiberglass or plastic suitable for storing potable water. temperature transfer and earth shifts will crack the concrete. cant use concrete for anything other than non potable sea because of integrity issues
I know that they do make a spray that you can use,I'm not sure of the given name of it ,but your local hardware store should be able to help you find somethig that will work. I enjoy a 1000 gal. tank & a 500 gal. tank made from concrete and never have any prblems with cracking or leaking.The major thing is to make sure you capture all of the air out of the concrete foam when your pouring the concrete.You can do that by taking a sledge hammer and tapping the side of the foam while you are pouring the concrete. You can use a product called THOROSEAL. Thoroseal is a cement base, micro-porous (breathing) , seamless coating used to fill, seal, waterprooof, and protect an assortment of substrates including cast-in-place and pre-cast concrete.

Answers: Use lots of rebar and telecommunication mesh, thick walls, and fly ash to strengthen the concrete. Order the fly ash mixed in the concrete, and a vinyl admix if they hold it. make sure the tank is poured contained by place so it can conform to the irregularities of the soil around it. One thing more to do is to line it beside liquid plastic or a tar sealer on the outside but for poured in place. Would it not be easier to get a considerable plastic tank and put that in the ground? Backfill near lots of sand to keep it from moving. It may be cheaper than the concrete, and easier to replace or repair, or remove later. I plan to put one beneath ground where the old cess pit used to be. I plan on running the Ac copper pipe around it to precool it formerly going into the condenser. The tank will be used to store rainwater, and some shower water after it is filter and run through an above ground concrete tank filled beside reeds. Is yours for primary drinking water, or toilet flushing?
